How to Interleave Multiple Lists of Equal Length in Python?

Interleaving Multiple Lists of Equal Length in Python

In Python, there are instances where you may need to combine multiple lists of the same length into a single interleaved list. For example, suppose you have two lists, [1, 2, 3] and [10, 20, 30], and you want to transform them into [1, 10, 2, 20, 3, 30].

One simple approach to achieve this is by leveraging Python's zip() function, which combines corresponding elements from two iterables into tuples. By applying zip() to your lists and looping over the resulting tuples, you can efficiently construct the interleaved list. This can be expressed in the following code:

[val for pair in zip(l1, l2) for val in pair]

where l1 and l2 represent the input lists.

For cases involving more than two lists, the same concept can be extended using the asterisk (*) operator in conjunction with zip() to achieve interleaving among multiple lists. This can be represented as:

lists = [l1, l2, ...]
[val for tup in zip(*lists) for val in tup]

By utilizing these techniques, you can conveniently interleave lists of equal length in Python, offering a concise and efficient solution to your data manipulation requirements.
